WHM >> Account Functions >> Modify an Account I am disappointed to see that in the latest WHM stable version 8.8.0, the domain rename problems are still not corrected. If you try to rename the domain of an account, what the WHM will do is to simply create another DNS zone for the new domain, leaving the old one in the system (instead of removing it). After renaming the domain, you will also find the account disappearing under "WHM >> Account Functions >> List Accounts" although the account is still valid. For now, the fastest way to rename a domain is to: 1) terminate the existing account and re-establish it with the new domain. Of course, using this method, you will lose all data. So this method is only suitable if your account is new and has nothing much inside. 2) park the new domain name as a "parked domain", leaving the old domain name intact.
